The Scottish international is desperate for a Champions League experience.
The 25-year-old enjoyed a fantastic campaign last term, bagging 40 goals and putting himself back into the international frame. Despite that, there remains one objective the Scottish international has yet to realise.
“The Champions League group stages remain the only box that I haven’t ticked. Yes, that’s the one,” said Griffiths.
“You don’t really make it as a player unless you’ve played in the Champions League. The closest I’ve been is the Malmo game last year when we very nearly achieved our goal. Hopefully this time we can go one round further and manage to get into the group stage.”
The Hoops striker has yet to establish himself at international level despite his excellent club form, and regular appearances in the Champions League could help make that a reality.
“The next step for me is to play in the Champions League and to become a regular for the national team,” Griffiths added.
“I need to score at that level and I obviously can’t do that if I’m not there. If I can score in the Champions League then I can put my name forward to lead the line for Scotland as well.”
Celtic’s last adventure in Europe’s premier competition came in the 2013-14 season, with then-manager Neil Lennon guiding the club to the last 16, and pressure will be on current boss Brendan Rodgers to return the Hoops to the promised land.
The former Liverpool manager is highly regarded for his attacking brand of football and he will need to hit the ground running with Celtic’s Champions League campaign beginning in the second qualifying round next month.
Griffiths will undoubtedly play a major role in any success at Parkhead next season and Rodgers will be hoping the front man’s burning ambition will help propel the Hoops on another successful European foray.
